CUTTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 353. dated November1836- Appiication filed February 15, 1886. Serial No. 191,994.

To all whom it may concern:

Beit known that I, EZRA Korea, a citizen of the United States, and aresident of Palisade, in the county of Minnehaha and Territory ofDakota, haveinvented certain new-and useful Improvements in CuttingApparatus; and I do hereby declare that the following is a full, clear,and exact description of the invention,

.which will enable others skilled in the art to which it appertains tomake and use the same, reference bein g had to the accompanyingdrawings, which form a part of this specification, and in which- Figure1 is a perspective view of my improvedsickle-bar. Fig. 2 is a plan viewof the same. Fig. 3 is a plan view of the sickle-bar with the cutter-barremoved. Fig. 4 is a similar View with the lower or rigid cutter-barremoved. Fig. 5 is a plan view of the rigid cutter-bar; and Fig. .6 is avertical cross-section on line as m, Fig. 2.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to sickle-bars for harvesters, reapers, andmowers; and it consists in the improved construction and combination ofparts of a sickle-bar in which the blades, which are secured to theguards or fingers, are secured at their inner ends to a bar similarly tothe cutter-blades, which bar rests in a groove in the finger-bar, sothat after removing the cutter-bar for the purpose of sharpening thecutter-blades the lower or rigid cutter-bar may be removed from thefinger-bar and have its blades sharpened, as hereinafter more fullydescribed and claimed.

In the accompanying drawings, the letter A indicates the sickle-bar orfinger-bar,whic h is provided with the usual guards or fingers, B, andwhich is formed with the usual groove,G, for the cutter-bar, the cuttersD of which bar are secured to the bar E in the usual manner, and are ofthe usual construction. Each guard or finger. B is further provided witha groove or notch, F, in front of and below the groove 0, except theouter or end guards, in each of which the groove does not extendentirely across it, but leaves theouter portions solid, forming a stopor shoulder, G, in each outer finger. Each of the guardsis also providedwith the ordinary slots, H, the forward por No model.) Patented inCanada June 1, 1886, No. 24,204.

tions of which are provided with recesses I, of less width than the endsof the slots.

The bar J, upon which the lower cutters, K, are secured, fits and restsin the grooves F, with its ends bearing against the stops or shoulders GG, and the forward ends of the lower or rigid, cutter blades are formedwith lips or tongues L, which will fit into the recesses in the fingers,retaining the blades K in their position. It will thus be seen that thereciprocating cutter-bar may be slid out through its groove in the usualmanner, whereupon the lower rigid cutter-bar may be pushed up out of itsgroove back into the groove for the reciprocating cutter-bar, thetongues of the lower cutter-blades sliding out of their recesses, andthe lower cutter-bar with its blades may now be slid out to one sidein'the same manner as the reciprocating cutter-bar and be sharpened orrepaired, as it is desired. By having the lower cutter-blades securedinthis manner the necessity of removing one of the guards and of thereuponremoving the cutter-blade and inserting another by riveting it upon thefingeris avoided, and the lower cutter-blades may be sharpened andrepaired in the same manner as the cutter-blades upon the reciprocatingcutter-bar.

The tonguesat the outer ends of the lower placement of the outer ends ofthe lower cutters, and the rear or inner ends of the cutter blades,being secured to .the bar, which is prevented from lateral displacementby the shoulders at the ends of the groove, and which is held in placeby the reciprocating cutter-bar, will be prevented from being displaced,so that the lower cutters are as securely fastened to the finger-bar asif they were riveted to the fingers, and at the same time are moreconveniently secured for repairing or sharpening.

It will further be seen that by having the notches or grooves for thestationary bar below the groove for the reciprocating bar the stationarybar cannot be forced back against the reciprocating one, thus tending tobind it and cause it to run harder, as would be the case if the bottomsof the grooves were on a level, ashas been the case with devices of thiskind.

The shape of the fingers, as well as of the cutter-blades serve toprevent any lateral dis- ICO' lower and upper cutters and theirfastenings cutter-bar groove, the groove in each of the to the bars, maybe changed as desired withend guards not extending entirely across them,

out changing thespirit of my invention,which a bar in said groove havinga series of cutters I5 is applicable to any style of sickle-bar and to 5any style of cutters.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States In a cutting appparatus, thecombination of IO a fiuger-bar provided with guard-fingers, each of saidfingers being provided with a groove in front of and extending below thelevel of the secured thereto, and a reciprocating bar having cutterssecured to it.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
